1 Claim.

'This invention relates to cushions, and its general object is to provide a cushion primarily designed for the seats of furniture and vehicles, that is not only extremely comfortable, but will last for a prolonged period of time under hard usage and can be easily and quickly repaired in the event of damage or breakage of any of the parts thereof.

Another object of the invention is to provide 0 a seat cushion that includes coil springs and means to prevent the springs from breaking or wearing through the seat covering.

A further object of the invention is to provide a seat cushion that includes means to relieve strain of excess pressure upon the springs and to distribute the pressure somewhat evenly throughout the entire spring construction.

A still further object of the invention is to pro vide a seat cushion of the character set forth,

that is simple in construction, inexpensive to manufacture and extremely efficient in operation and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a top plan View of the seat cushion which forms the subject matter of the present invention with parts broken away.

Figure 2 is a bottom plan View.

Figure 3 is a front View with the covering removed. l

Figure 4 is a sectional View taken approximately on line 4-4 of Figure 1. y

Referring to the drawing in detail, the reference numeral l indicates the base frame of my cushion seat which follows the configuration of the seat proper and it will be noted that the seat as shown is of the usual elongated formation, which is generally used in motor vehicles, however, I want it understood that my invention can be applied to furniture seats as well as cushions of any type, and also for the backs of seats without departing from the spirit thereof.

The base frame may include front and rear strips, and end pieces and secured to the top of the base frame is a sheet of screen wire 2 which 55 covers the space between the front and rear strips and end pieces of the base frame as clearly shown in Figure 4 of the drawing.

Secured to the front strip of the base frame is the forward horizontally bent end portion 3 of a sheet of metal which extends from the portion 3 at an upward inclination for termination above and in alignment with the rear edge of the rear strip of the base frame. lThe upper rear end of the inclined portion 4 is rolled upon itself at intervals in the length thereof to provide hinge barrels 5 for a purpose which will be presently apparent. The inclined portion 4 is likewise bent or crimped longitudinally intermediate its upper and lower edges to provide a flange 6 depending from the lower surface thereof, and this iiange is provided with openings arranged at intervals throughout its length for the purpose of receiving the upper end convolutions of coil springs 7 arI ranged in parallelism with respect to each other Y and which have their lower convolutions fixed to a bar 8 that bridges the end pieces of the` base frame and of course is fixed thereto as shown in Figure 2.

Arranged adjacent the group of coil springs 7' is a group of coil springs 10 which likewise have 80 their upper convolutions secured to the inclined portion 4, while the lower convolutions of the springs 10 are fixed to the rear strip of the base frame by any well known means, and it will be noted that the coil springs l0 are disposed to the rear of the coil springs 7.

Aligned with the hinge barrels 5 for the purpose Iof receiving a hinge rod ll are hinge barreis 12 that are formed with the rear end of a metallic sheet which provides a reinforcing cover plate 13 for the spring construction. The cover plate 13 as well as the portion 3 are each provided with rounded forward corners, and the cover plate is provided with a bead that extends along the front edge and end edges thereof.

The cover plate is likewise bent or crimped midway its ends to form a depending nange 14 disposed adjacent the forward edge thereof, and the flange 14 has arranged therein at spaced intervals a plurality of apertures to receive the upper convolutions of a group of coil springs 15 which have the lower convolutions fixed to the upper surface of the inclined portion 4 as clearly shown in Figure 4 which likewise discloses the fact that I also provide a group of coil springs 16 which have their upper convolutions secured to the under surface of the cover plate 13 adjacent its forward edge and the lower convolutions of the coil springs i6 are fixed to the portion 3 of the sheet of metal which includes the inclined portion 4.

The structure thus far described may be covered in any well known manner, and I have shown a cover which includes an upholstered upper porn tion 17, and front, rear and end pieces secured to and depending therefrom.

From the above description and disclosure of the drawing, it will be obvious that I have provided a cushion which Will stand hard usage, but is extremely comfortable due to the particular arrangement of the coil springs, and the inclined portion 4 of the sheet of metal that includes the portion 3 and which may be termed the base plate, due to the fact that it is xed to the base ange as clearly shown in Figure 4. It will also be apparent that it is impossible for the coil springs to break through the covering, as the cover plate 13 prevents such a casualty, and the life of the cushion is prolonged due to the fact that webbing has been dispensed with and use is made of a sheet of screen Wire and the sheets of metal as set forth.

It is thought from the foregoing description Leeip that the advantages and novel features of my invention Will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is:

In a cushion, a base frame, a sheet of screen Wire secured to the base frame, a base plate having its forward portion secured to the base frame, an inclined portion rising from the forward portion, a cover plate hingedly secured to the upper and rear edge of the inclined portion and extending forwardly therefrom, resilient means between and connected to the cover plate and that portion of the base plate secured to the base frame, means bridging the ends of the base frame, coil springs secured to the last mentioned means and the inclined portion respectively, coil springs between the inclined portion and base frame, and coil springs angularly disposed between the inclined portion of the base plate and the cover plate.

CHARLES H. SMITH.
